Carrier introduces the latest version of its Hourly Analysis Program (HAP) software, incorporating new calculators and simulation models. Among these enhancements is the ability to model new plant configurations using air-to-water and water-to-water heat pump chillers as well as service water heating (SHW) systems, and the automatic calculation of ventilation airflows per ASHRAE Standard 62.1-2010 and minimum equipment efficiencies per ASHRAE Standard 90.1-2010. Carrier the world’s leader in high technology heating, air-conditioning and refrigeration solutions, is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).
“We are continually updating and improving our eDesign Suite of software tools so customers have the most comprehensive resources for designing and analyzing heating, ventilation, and air-conditioning (HVAC) systems,” stated Greg Alcorn, vice president, commercial sales & marketing, Carrier. “With the HAP v4.7 update, we focused on three main themes: simulations, systems and standards.”
With the worldwide focus on green building, owners and building designers are increasingly turning to heat pump technology to cool and heat medium to large commercial buildings. HAP v4.7 expands plant modeling features to support green building designs. Three new plant types are offered - chilled water / hot water changeover plants using air-to-water or water-to-water reversible heat pump chillers; dedicated hot water plants using air-to-water or water-to-water heat pumps; and hybrid hot water plants, which combine hot water boilers with air-to-water or water-to-water heat pumps.
In hospitals, hotels and schools, heating and cooling is a significant portion of total building energy use. HAP v4.7 now expands simulation modeling capabilities in this area, offering modeling for a standalone plant, or a plant serving combined space heating and SHW loads. Hour-by-hour hot water consumption profiles, equipment characteristics and controls can be modeled to calculate detailed energy performance.
In addition to energy performance, HAP v4.7 assists with calculating code-compliant outdoor ventilation airflow rates, a key task when designing HVAC systems. Default room ventilation rates based on ASHRAE Standard 62.1-2010 requirements and ventilation flow requirements for Standard 62.1 Ventilation Rate Procedure are addressed in the new version. In addition, features are available to automatically set DX equipment efficiency based on ASHRAE Standard 90.1-2010 minimum efficiency levels, which is an important timesavings when working toward Leadership in Energy and Environmental Design (LEED®) Energy and Atmosphere Credit 1 analysis or ASHRAE Standard 189.1 analysis.
